Take of mercury one part, sulphur two parts and iron powder three parts and rub them with the juice of the Indian aloe and after 6 hours transfer the mass to a brass-vessel and cover it with the leaves of the castor-oil plant. At the end of an hour and a half the mass will become heated. It is then buried under a heap of paddy grains and taken out after three days and then powdered very fine and the contents passed through linen.¹ All the three varieties of iron are thus completely killed. Gold and other metals can be killed by this process after being reduced to fine powder like iron.
